R help - Dec 2012 - Troubles with subset()

All,
I have the attached dataset which I read from SPSS and transformed a little
bit using the attached script. I am trying to run a logistic regression
using glm() on a subset of my data. When I run the logistic regression on
the whle dataset, it runs OK. As soon as I try to run on the subset, I get
an error message related to different lengths of variables. Any idea why
this might be so? Thanks for your inputs. V

Please paste the code, as it was removed by the server.

Most likely, it comes from the fact that some terms in the formula refer
to variables in the 'data' argument, and some do not.
